What reviewers think
Magazine reviewers and YouTubers have tried this product—so we've summarized their strongest opinions below.
How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.

ATC-3
- Positioning: The entry-level stereo line-control amplifier designed for affordability and ease of use.
- Description: Features a simple SRPP design with a reinforced buffer stage and a quick recovery diode power supply that offers very low noise. Compared to the more advanced ATC-7, it has fewer features and lower output capability, making it best for small rooms and buyers with a tighter budget and basic functionality needs.
ATC-7
- Positioning: The mid-range stereo line-control amplifier focused on precise signal handling.
- Description: Uses dual 12AX7 and 12AU7 valves to deliver precise control, a wide frequency range, and low distortion. Compared to the entry-level ATC-3, it offers enhanced performance and output voltage while leaving the high-powered driver role to the ATM series.
ATM-1S
- Positioning: The stereo power amplifier built to deliver dependable and balanced performance.
- Description: Uses a traditional Mullard phase inversion circuit with 6CA7 valves and robust Hashimoto transformers to achieve 36W per channel with solid headroom. Compared to the flagship mono BLOCK ATM-3211 and the preamp line (ATC-7 and ATC-3), it strikes a balance in cost and power.
ATM-3211
- Positioning: The high-end mono power amplifier engineered for maximum power delivery.
- Description: Uses a five-year developed 211 triode push-pull circuit that produces 120W output with a wide frequency response and premium hand-picked components. Compared to the stereo ATM-1S and the preamp ATC series, it offers higher output power and superior build quality.

Burson
Hi-Fi companies are spoiling headphone enthusiasts with a wide range of choices, but they often overlook near-field audiophiles who listen to speakers in small studios or from their desktops. Instead, near-field audiophiles are left with subpar Class-D amps or active speakers. Alternatively, they have to settle for larger Class-AB amps that disrupt the aesthetic of their setups. The Burson Funk breaks that rule by offering a combination of exceptional performance and a design that fits seamlessly into any living space.
Burson is a hifi brand recognized for its modular op-amp design that allows users to easily swap components to customize their sound signature.
Expand Details
Our Summary
Product Strengths
- Good sound quality, especially in the midrange, leads to vivid and well-formed vocals
- Versatile, it works well with both efficient headphones/IEMs and moderately powered speakers
- Compact design and good build quality, with the chassis acting as a heatsink
- Ability to roll op amps allows users to customize the sound signature
- Ample power for most headphones and nearfield speaker setups
- Only one RCA input, which may be limiting for some users
Product Considerations
- Speaker amplifier power (35-45W) might be insufficient for power-hungry speakers or larger rooms
- The base model op amps are sonically inferior to upgrade options
- Mild turn-off thump present
Comparisons (according to reviewers)
- The Funk has a narrower but deeper soundstage with better imaging and layering than the Arylic A08 Pro
- The Funk has superior imaging, but less potential power output depending on the Arylic's power supply than the Arylic A07/A08 Pro
- The Funk is preferred for desktop speaker setups with Vivid opamps when compared to Schiit Aegir
Takeaway: The Burson Funk is a solid choice for people wanting good sound from both their headphones and speakers in a single, convenient unit. The ability to change the sound by swapping op amps is a welcome feature for those who like to tinker and upgrade.
